l-3-Hydroxyacyl-CoA dehydrogenase reversibly catalyzes the conversion of l-3-hydroxyacyl-CoA to 3-ketoacyl-CoA concomitant with the reduction of NAD(+) to NADH as part of the beta-oxidation spiral. In this report, crystal structures have been solved for the apoenzyme, binary complexes of the enzyme with reduced cofactor or 3-hydroxybutyryl-CoA substrate, and an abortive ternary complex of the enzyme with NAD(+) and acetoacetyl-CoA. The models illustrate positioning of cofactor and substrate within the active site of the enzyme. Comparison of these structures with the previous model of the enzyme-NAD(+) complex reveals that although significant shifting of the NAD(+)-binding domain relative to the C-terminal domain occurs in the ternary and substrate-bound complexes, there are few differences between the apoenzyme and cofactor-bound complexes. Analysis of these models clarifies the role of key amino acids implicated in catalysis and highlights additional critical residues. Furthermore, a novel charge transfer complex has been identified in the course of abortive ternary complex formation, and its characterization provides additional insight into aspects of the catalytic mechanism of l-3-hydroxyacyl-CoA dehydrogenase.

Figure 2.
Fig. 2. L-3-Hydroxyacyl-CoA dehydrogenase complexed with the substrate, 3-hydroxybutyryl-CoA. The ribbon diagram depicts the two-domain structure of an HAD subunit, with the first 200 amino acids comprising the NAD +-binding domain and the remaining residues comprising the C-terminal domain. 3-Hydroxybutyryl-CoA, shown in ball and stick representation, binds within the cleft between these two domains. The adenine moiety of coenzyme A is positioned adjacent to the helix-turn-helix tail ( 2- 3) of the NAD^+-binding domain, and the acyl chain is within the enzyme active site.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
